Abstract
A method implemented by computer means for determining a virtual wearer-ophthalmic lens-ergorama system associated with an optical function of an ophthalmic lens for a given wearer, comprising: a prescription data providing step, an optical reference surface data providing step, a virtual wearer-ophthalmic lens-ergorama system determining step, a criteria selecting step, a target value defining step, an evaluation step, and a modification step, in which at least one parameter of the virtual wearer-ophthalmic lens-ergorama system different from the base curve of the ophthalmic lens is modified, in order to minimize the difference between the target value and the evaluation criterion value.
